Frozen Piano
The sound of decay and renewal. Frozen Piano begins with a simple premise: leave an instrument to the elements and see what happens. The results are more fascinating than you might expect.
Our instrument engines
Layers
Layers turns sound into a shifting landscape, each concentric circle a doorway into overlapping textures. Ambient strings drift, synth pads swell, and subtle harmonics weave between layers, all guided by a central blend control that lets patterns fold, overlap, and blur in real time. It’s an engine for crafting soundscapes that feel alive, patient, and just a little unpredictable.
Threads
Threads operates as a compact rhythmic ecosystem built around three independently sequenced layers. Velocity is shaped directly within each lane, adding human-like nuance to even minimal patterns. Layer-specific controls introduce subtle behavioral changes, allowing sequences to drift, lock, or reorient themselves with understated musicality.
Chords
Chords reimagines the chord engine, making harmonic exploration fluid and responsive. Layers of sound can be blended and manipulated in real time, offering control over voicings, progressions, and textures. Experimentation is rewarded, letting simple inputs blossom into unexpected harmonic landscapes.
Orbits
Orbits puts four sounds in motion, letting them collide, fold, and drift across a single XY pad. Every nudge blends layers in real time, sparking textures that ripple, slide, and evolve with effortless energy. Subtle gestures unlock layered atmospheres and playful sonic experiments, creating patterns that feel alive, flexible, and just loose enough to surprise.
Disperse
Disperse pushes four studio-string voices outward from a central pitch, sliding up to an octave with fluid motion. Chords stretch, fold, and collide, forming harmonies that drift and shift with subtle energy. Small tweaks guide the spread and interplay of each voice, unlocking layered textures, evolving intervals, and movement that’s loose, responsive, and just a little unpredictable.
Jupiter
Built on controlled turbulence, Jupiter turns cosmic churn into musical motion. Particles move with their own rules, colliding and drifting to form evolving textures and irregular rhythms. Chaos thickens into clustered patterns, structure returns in repeating streams, and the whole system moves with its own internal gravity.
